Application filed November zl, 1914. Serial No. 873,295.

T all whom it may concern:

Be it known that I, WILLIAM Enasros WILLIAMS, a citizen of the United States,

residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Steel Box-Cars, of which the following is a specification.

The object of my invention is to produce a very strong, cheaply constructed and light weight box car and one that will be neat in appearance and have various special merits as will be noticed from the specification and drawings, and as. set forth in the claims.

Theinvention consists in the construction and combination of parts as set forth in the claims.

Fig. 28 is a section on the line 2828, of Fig. 27.

With my invention, I prefer to form the side sheathing of the roof of the car, in such Ia manner that the sheathing and the roof themselves will furnish all of the strength and stiffness required without the framevwork which has hitherto generally been used, and by doing this, I am enabled to make a lighter weight car for the same service and also .to provide a little more room within the clearance ordinarily given for box cars, and further, I am enabled thereby a sheathing which depends upon the framthe intervening space.

My invention makes the outside of the car nearly smooth and of such a nature that it will shed the water more completely and furnish no horizontal or inclined shoulders to catch and hold moisture and induce corrosion as .is the case with some other designs of steel box car construction.

The corrosion of the metal of which steel cars are made is the greatest objection to the use of steel in the manufacture of cars, and corrosion is greatly delayed and reduced by avoiding external ledges and crevices from which water will not quickly flow. Where the sheathing is thin metal, such ledges and joints may cause the whole structure to be seriously weakened by corrosion while the body of the thin metal is substantially intact; and it is thought that the construction here set forth minimizes this evil.

It is desirable with many classes of goods which are shipped in box cars, to have the car insulated from too high temperatures and also it is desirable that the inside sur face of the car should furnish a wooden surface for contact with the loading instead of a metal surface, and my construction permits the use of a wooden insulation on the inside of the car together with an air space and yet consumes less space for the wall thickness of thesides of the car than is ordinarily used with a car having the same rigid stiffness and general strength for the body of the car.

The manner of forming the steel ends of my car permits a lighter weight of metal for the same strength than any other construction heretofore used so far as I am aware, and at the same time provides a form which permits of Wooden insulation at a less expense than the steel ends heretofore commercially used, and also this construction is such that in sheathing the end there is less trouble in filling all the spaces and escaping the chance of leaving voids beneath the sheathing which might gather dirt and provide space for the permanent residence of insects 0r vermin which might at times injure the load of the car.

The roof section of In car, while it furnishes the necessary sti ness and strength for the top of the car Without other framing, is also of such a form as to take up by its own elasticity, any deflections produced by the yielding of the whole car bodywhen it receives severe shocks that all cars are required to meet at times. Many forms of metal roofs are seriously injured by the distortions produced in the car body and by severe shocks.

In a steel sheathed car it is desirable to memes stronger construction for the same metal along the side sill of the car than has heretofore been obtained by steel box car constructions.

In the drawings, 1 indicates the sheating for the sides of the car (see Figs. 1 and 2). This sheathing is made up of sheets which extend vertically and they are stiffened at suitable intervals by ribs or flanges 2 which are formed from the body of the sheet by suitable bending operations. The sheets are joined together as indicated by 3, Fig. 2 wherein a rib or flange of one sheet is embraced by the rib or flange member of the edge of the adjacent sheet, and thus when the sheets of the sheathing are in place on the car, the outside appearance does not disclose the line of the joints on the edges of the several sheets. At theends of the car the edge of the side sheathing bends around the end at the corner as indicated by 4.

The side sill of the car is made of two pieces, riveted together forming a section which might be termed a channel T section. This is shown most clearly by Figs. 3, 4 and -6. The lower piece of this side sill section is indicated by 5 and the upper piece by 6 and the rivets which join the pieces are in dicated by 7. These pieces 5 and 6 are first punched in the flat with series of 1 slots spaced along their edges at the intervals where occur the ribs 2 and 3 of the side sheathing or sidin of the car. When after these notches or s ots are made in the flat bars 5 and 6, the bars are bent to the form shown providing the flanges 8 of bar 5 and 9 of bar 6 to which there is riveted by the rivets 10 and 11, the siding 1. The flanges 2 and 3 of the siding passing through the slots in the pieces abutting against the wall 12 of the piece 5. 13 indicates the floor of the car made .of planks extending crosswise of the car and these planks are bolted to the side sill members by the bolts 14 at suitable intervals in the length of the car on the inside of the siding.

Wooden blocks or posts 15 are fastened by means of the bolts 16 to the flanges 2 and 3 of the siding. To these posts 15 there is fastened by the nails 17 the inside wooden sheating 18 of the car. In order that the post 15 may be held strongly against the outer wall of the siding, the post is formed with a beveled edge 19 (see Fig. 2) which induces the bearing of the post 15 against the siding when the bolt 16 is tightly drawn. The siding 18 does not extend clear down to the floor, but there is a gap between the mamas bottom edge and the floor sufliciently wide to permit of the cleaning out of the spaces between the ribs or flanges 2 of the siding. The bottom edge of the inside wooden sheathing is indicated by 20' Fig. 4.

The end of the flooring planks stop at the inside edges of the flanges 2 and 3 and between these flanges there are filler blocks of wood 21 which are cut out at 22 to accommodate for the rivet heads 10. Then after the flooring and blocks 21 are in place, a nailing strip 23 is run along and nailed to the floor and to the blocks 21, thus as sisting in holding the blocks 21 in place. However, blocks 21 are inserted before the floor is laid, and if this is done the rivet heads of the rivets 10 will then hold the blocks 21 in place. Pieces of tar paper 23 are placed in cont-act with the metal between the blocks 21 and floor 13 to insure a tight fitting joint there and to protect the metal surface from corrosion.

The car body bolster and cross bearers or needle beams as they are sometimes called, which are part of the underframing, 'are indicated by 24 in Fig. 4 and they are secured to the vertical web 12 of the piece 5 and to the horizontal webs or flanges of both pieces 5 and 6 as is indicated by 26 in Fig. 4. See also Figs. 23, 24 and 25.

The siding 1 (see Fig. 4) covers over'the outside of the pieces 5 and 6 which form the side sill and thus make, as it were, a box girder of the side sill at all places save at the door opening or between the door osts. Between these posts,I rivet on a plate2 ,(see Figs. 6 and 7) and thus this plate carries the box girder section the full length of the car. llhe top edge 28 of plate 27 is turned over to furnish a flush edge to engage the edge of the sliding door along the line of its clearance with the side of the car and at the same time it extends beyond the heads of the rivets which fasten plate 27 to the side sill members.

The siding 1 extends up and is fastened by the rivets 29 to the lower flange 30 of a 2 bar 31 which forms the side plate or eaves of the car. The Z bar 31 is reinforced by a pressed strip 32 which is riveted to the 2 bar by the rivets 33 and thus this piece becomes a part of the side plate itself and furnishes additional strength to it. The flange 34 of 32 (see Figs. 4 and 17) is formed to fit the corrugatedsheets 35 which form the roof.

The flange 36 of the 2 bar 31 is cut out v at the points 37 to clear the gutters of the corrugated roof sheets.

The roof sheets are fastened to the member 32 by clips 38, the vertical flanges of which are riveted to the side plate by means of the rivets 39 which pass through the clips themselves through the member 32 and the flange36 of the 2 bar. Thus, when the roof is secured to the car, the member 32 is secured to the Z bar flange by a double row of rivets. Rivets 40 secure the plates 38 to the roof sheet at the top or summits of the corrugations.

The left door post is made of a sheet metal member 41, (see Fig. 7) and it extends down on the outside of the sheathing and is fastened to the side sill by rivets 42 (see Fig. 5). This post has the projection 43 which acts as the door stop and it has a wing 44 bent around into the door aperture and with an overlapping flange 45. A wooden post 46 is placed in the embrace of the flange 45, and is bolted at suitable intervals as indicated by the bolts 47. The post 41 is mutilated and bent at the bottom in a manner to provide a flange 48 (see dotted line in Fig. 7) which extends horizontally underneathvthe floor and is riveted by rivets 49 to the side sill.

The post 41 is cut away at the top as indicated by 50, to fit under the flange 30 of the Z bar 31 of the side plate, but the sections 44 and 45 (see Figs. 14 and 15) extend up to the inside of the horizontal web of the Z bar 31. A gusset plate 51 shown in dotted lines in Figs. 8, 14 and 15, connects the main flanges of post 41 to the A bar. These parts are secured together by rivets 52 and 53. An angle piece 54 fastened by rivetsv 55 to the flange 44 of the post, connects this flange to the web of the Z bar 31 by rivets 56, thus the post is securely fastened to the side plate.

The door rail or track for the door is indicated by 57 .and is a Z bar riveted to the flange 30 of the side plate. projection 43 is bent inward at 58 Fig. 15, to bring it underneath the door rail 57 and thus shut off the rain from the cavity within the projection.

The right hand door post is indicated by 59 and it is also provided-with a flange 60 in the door opening and an embracing The post flange 61 which embraces a wooden post 62 secured in place by the bolts 63 and 64, (see Fig. 7). fastened by rivets 65 to the side sill (see Fig. 5) and above the side sill a flange 66 of the part is bent outward to form a spark strip (see Fig. 7) and at the top where the flange 66 joins the flange 30 of Z bar 31 this spark strip section is cut loose for a short distance right on the line of the edge of the flange 30 of the Z bar and the body section of the top end of the post is then bent inward to extend on the inside of the flange 30 of Z bar and rivets 67 fasten the top of the post to the 2 bar. Angle plates 68 shown in dotted lines in Fig. 5 fasten the flange 60 to the web of the 2 bar side plate in the same manner as the angle plate 54 does to the left hand post. The bottom of post 59 is mutilated and bent similarly to The lower end of this post 59 is 71, to prevent snow the post 41 producing the flange 69 fastened by the rivet 70 to the side sills, (see Fig. 7). Thus the door posts are secured to both the side sills and the side plates.

The roof sheets 35 are made of corrugated sheets corrugated relatively very deep and extend in an are from side plate to side plate all fastened as has been indicated, so securely to the side plates that the roof sheet itself becomes the entire roof structure of the car. The ends of the roof sheets where they pass down onto the member 32 are flanged over'as is indicated by blowing underneath the ends of the sheets.

A running board 72 is fastened to the roof sheet in any suitable manner, but I prefer to fasten it by means of the saddle blocks 73 bolted to the summits of the corrugations of the roof sheet at suitable intervals as required, (see Fig. 1).

The end of the car is made of a corrugated sheet 74 made in. several pieces when desired and the corrugations extend cross- Wise of the car (see Figs. 3, 20 and 22). These corrugations are made with substan- "tially flat horizontal sections and flat vertical sections thus-becoming almost a series of letter Ss having square block sections as is indicated by 75 for the horizontal sections and 76 for the vertical sections. The purpose of this form of the main body of the corrugated end is to get as much metal on the front and back surface of the sheet as is possible thus forming the equivalent of a series of box girders which form has less metal in the neutral axis to resist an end thrust of material in the car, than is the case when the ordinary form of curved corrugation is used. This method of corrugating the end sheets for the ends, obtains a greater section modulus of resistance to resist bulging with a light sheet than can'be obtained with the curved corrugations with a muchheavier sheet. A sheet of metal 5" thick corrugated as I have designed, will resist a greater end thrust of the car load than can be sustained by a it," sheet having the old corrugations. At the ends of the end sheets, I press down alternate corrugations as indicatedby 77, Fig. 20, thus making the vertical sections 76 all in one plane where the ends of the sheets join the corner post and in doing this, the horizontal ortions 75 are doubled on themselves mal lng the flange 78 approximately half the width of the portion 75, (see Figs. 11 and 20).

I prefer to make the corner post of the car out of angle sections as is indicated by 79. One leg 80 of this angle embraces the siding and leg 81 embraces the end. A flange 4 of the siding 1 is curved around fitting the inside faces of the lines of the angle post 7 9' and for the greater art laps over the ends of the end sheet, thus y means memes of the flange 4 the thrust of the end is carried to the siding independently of the rivets which may fasten the siding to the corner ost.

p On the inside of the angle corner post, there is bolted-a wooden post or block 83 secured in place by the bolts 84. This block 83 is notched out to receive the ends of the boards 85 ,of the Wooden sheathing 18 and it is also notched out at intervals to embrace the flanges 78 of the end sheets.

The angle post 79 is fastened to the flange 30 of the 2 bar by means of the gusset plate 86 (see Figs. 3, 4 and 10 and 16), the flange 80 of the post 79 being cut away at the point 87, Figs. 4 and 16, to join the flange 30 of the 2 bar. A piece of tar paper or other suitable material .88 is placed in this joint to keep out the water and make a tight joint and an angle plate 89 shown in dotted lines in Figs. 3 and 16 and in full lines in Fig. 4, secures the flange 81 of the corner post to the web of the side plate by means of rivets 90 and 91. a

The corrugated end sheet may be made to extend up into the roof sheet and become itself, the end plate of the car box, but I prefer to make the plate of a separate sheet the end of which is shown in Fig. 21 and is indicated by 92, for the vertical Web portion and 93 for the curved portion on to which the end corrugation94 of the roof sheet fits as is indicated by Figs. 3, 4 16 and 22. This end plate is notched out at 95 to fit the side plate member 32 Where it is notched out at 96 (see Figs. 17 and 21). A junction angle block97 shown in full lines in Fig. 4 and in I dotted lines in Fig. 16, join the vertical flanges 36 of the 2 bar side plate to the end plate 92 by means of rivets 98 and 99. Thus a very strong corner is produced.

The flange'4 of the siding where it turns around the end is notched out at 100 (see Fig. 19) to clear the corner 101 of the end plate, Fig. 21.

. When the ends of the car are required to be sheathed with wood, every other corrugation is filled with arectangular block as is indicated by 102 (see Figs. 3' and 22) and v these blocks are fastened in place by some oval strips running vertically on the inside as is indicated by 103 and they are fastened to the corrugated sheets by the rivets 104.

.Over the blocks 102 there extends the In the event that the wooden sheathing is not used for the end, my flatly corrugated 13c end sheet is more desirable than the round faced corrugated sheet might be as regards injury to loading of furniture and other articleswhich might be jolted heavilyqin contact with the end. i

as the siding is stifiened (see Figs 5, 6 and 26) wherein 108 indicates the door sheet, and 109 the ribs.

locking strip as is indicated by 110 of The door sheet or sheets have a 2 bar frame having'vertical member 111 and the horizontal members 112. This frame is connected at the corners by Z barangle blocks .113 and the door sheets are clamped on the inside of this frame by means of the angles 114 (see Fig. 7) on the inside or vertical members and by an angle 115 crossing at the top (seeFigs. 6 and 7) and at the bottom by a 2 bar section 116. Running across the door in the middle section there is a 2 bar cross piece 117. The-cross piece angle 115 and the cross piece A bars 116 and 117 are notched out the depth of the flange 109 of the door plate so as to have one flange of the Z bar bear against the plate surface of the door sheet. Filler blocks 118 and 119 made of wood are fitted in to beembraced by the upward projecting flanges of the as beingiriveted.

The d'oori's supported by the hangers 120' 2 bars 116 and 117. The purpose of this wooden-filling is to furnish surface to receive the impact of articles that may be improperly loaded and also to aid in the stiflening of the door.

' The several parts which compose thedoor are riveted bolted or spot welded together as desired and are shown in the drawings I having rollers which run 'on the door rail 57 which is riveted to the side plate. The bottom of the door is held within brackets 121 and 122 and by additional brackets on the. body of the car which are not shown.

Brackets 121 and 122 are bolted as is indicated by the bolts 123 Fig. 6 to the side sill of-the car. These bolts are covered up on the inside by the flooring and when the door is closed the door itself. covers the. outside, thus thebrackets can not be removed when the door is closed. B'olts 124 secure the botposed and may be taken ofl' by robbers who tom flange of the brackets and they are extakethe trouble to do so, but even when they are removed, the brackets themselves are still held, the bolts '123 which sustain practically all of the load and the bracket v These ribs run verticalliy of the door. This doorsheet may be .ma e in' owing to the location there at this point of the right hand door post.

Extending along the right edge of the door there is a spark strip 126 (see; Fig. 7) which has a flange 127 that interlocks with the flange 66 of the right hand door post 59 thus closing the space against flying sparks which come from the locomotive. This spark strip126 is fastened to the side of the door by rivets or by any suitable means.

At the junction of the end and the side sill (see Fig. 25) I provide a casting 128 of any suitable material, but preferably of malleable iron or cast steel. This casting has a flange 129 that is-secured to the Wall 12 of the side sill and the flange 130 which is secured to the end sill 131. A diagonal brace made of channel iron of any suitable form as is indicated by 132 is connected to the casting 128. A lip or flange 133 of a casting 128 abuts against the end of the At the bottom edge of the end sheet 74, i

I rivet an angle 134 (see Figs. 3 and 22) which angle has its lower leg covering the end sill 131 and is riveted thereto.

Inlay, when desired, reverse the direction of this angle as is indicated by the dotted lines 135 in Fig. 3. By placlng a heavy angle at the bottom of my end sheet, I secure a heavy piece of metal to encounter any severe strains that may come about from heavy iron bars in the bottom of the car or by damage that might be inflicted upon the end of the car by breaking of the coupler connections; thus I am not compelled to carry a heavy sheet up the whole end where it is not needed, but I obtain safety by the insertion of the heavy angle 134: as indicated.

Where the body bolsters and the cross bearers or needle beams of the underframe, join the side sills, I reinforce the side sills a short distance by angles indicated by 136 (see Figs. 4, 6, 13, 23 and 2 1) wherein 137' andl38 indicate the rivets which secure the parts together. The cross bearers or needle beams are indicated by 139 and the body bolsters by 140, and both have built up members along their upper margins and where they join the side sills there are angles or flange members having horizontal flanges as is indicated by 141 and these flanges are cut away Where the junction of the side sill is made and then on the top there is riveted a cover plate 142. The numeral 142 indicates the cover plate for both the needle beams and the body bolsters. The vertical flanges 143 of the cross bearers or needle beams and the corresponding flanges 144 of the body bolster are reinforced by angle plates 145 shown in dotted lines in Figs. 23 and 24, the numeral 145 beingused in both figures. Rivets 146 se cure these angles to the several members.

By using the short reinforcing angles 136 where the cross bearers and body bolsters join, the side sills, I may use on an average a much lighter weight side sill and yet secure a more-rigid construction of the car than is otherwise possible and further this reinforcement at these plates guards against the weakening that might be produced by corrosion since corrosion is more likely to take place at junction points of the members thlzlm along the smooth section of the side s1 Across the door opening, I fasten on the angle plate 147, Fig. 8, which furnishes a shoulder against which the edge of the door may engage in the event of a severe extraneous pressure coming upon it to force the door inward into the car beyond the strength of the door hangers to resist.
